If you need to trawl through your production server event logs. Here’s a quick tip for extracting just the entries for a given date range using LogParser. BTW Visual LogParser is a must have, it even downloads and automatically installs the latest version of LogParer from MS.

SELECT TimeGenerated, SourceName, ComputerName, Message FROM C:\Downloads\May09-ErrorLog\AppLog\*.evt WHERE TimeGenerated BETWEEN timestamp(’04/04/2009′, ‘dd/MM/yyyy’) and timestamp(’06/04/2009′, ‘dd/MM/yyyy’) ORDER BY TimeGenerated desc
